If you have raw point cloud data, for example .pts, .xyz, .fls, .ptx files etc. You can index these files into a usable point cloud format for Revit externally without even opening up Revit. You will be using exactly the same tool used within Revit, but it will mean you can continue to use your workstation for other activities, without occupying Revit. You still need an installation of Revit, although unofficially it may be possible just using the 'AdPointCloudIndexer.exe' which is a 262kb file stored in your Revit installation folder.
